Breast Cancer

Among all cancers ladies, he takes the ultimate place. In most cases, breast cancer develops inside the presence of precancerous changes. This is primarily a benign mammary dysplasia and papilloma ducts.

Breast cancer is represented macroscopically nodular and diffuse forms, as well as cancer of the nipple along with the nipple from the field (Paget's disease in the breast). For the nodular cancers are seen as a the node creating a diameter up to several centimeters. In some cases, a tight knot, is permeated with whitish layers tissue penetrating in to the surrounding dimply skin, in others - a soft, juicy around the cut, splits easily. Diffuse cancer of prostate is covered for the considerable distance, the contours from the tumor are marked bad. Sometimes the cancer invades your skin and forms about the surface of decaying mushroom formation - a cancerous ulcer. In certain instances, the tumor spreads over the surface with the breast and the iron is included with a dense shell.

In histological structure would be the following varieties of breast cancer:

• noninvasive: intralobular and intraduct;

• infiltrative.

Noninvasive breast cancer may be intralobular (lobular carcinoma in situ), and intraduct (ductal carcinoma in situ).

Infiltrating (invasive) cancer is seen as an varying levels of tissue and cell irregularities, which allowed to distinguish different amount of malignancy. This type of cancer include, particularly, infiltrating ductal and lobular carcinoma, which often gets the structure of scirrhus, as well as Paget's disease.

Causes of Breast Cancer.

The causes of breast cancer often are hormonal changes inside body: the entry into menopause, when there is an engaged restructuring with the hormonal regulation in the woman, the ovaries lose their activity, decreased manufacture of progesterone and estrogen, your body is certainly going through, "hormonal crisis." The mammary gland and endometrium (lining in the uterus) are most responsive to these changes, the breast growth begins to dissolve and stay replaced by fat.

Scientifically established how the female hormones estrogen-, plays a key role inside the progression of breast cancer. The excess hormones inside body produces a favorable background for developing the sickness. The least active hormones estrogen behave in pregnancy and after birth - during breastfeeding. It is proved how the birth and prolonged breastfeeding (greater than twelve months) to lessen the risk of developing breast cancers. On the other hand, abortion lead to hormonal "explosion" inside a woman's body that will trigger the growth and development of tumors. So far there is no consensus in regards to the impact for the continuing development of tumors of hormonal contraceptive drugs, yet it's belief that these drugs reduce the potential risk of developing breast cancer, but increase potential risk of developing cancer with the female genital organs, and osteoporosis. In addition predisposition to cancer of the breast may cause harmful environmental factors: the planet, as well as inflammatory diseases previously deferred breast - mastitis.

In addition, patients which has a group of first-degree relatives with breast cancers (mothers and sisters) likelihood of creating a tumor increasing by more than half - familial forms of cancer.

Benign breast diseases like fibrocystic breast disease, or fibroadenoz intraduct papillomatosis alone do not cause cancer, but as well, create an unfavorable background because of its development.

The cause of cancer of the breast could be the results of radiation, such as irradiation of the chest for other diseases (lung tumors, the lymphatic system), prolonged and frequent chest X-ray studies on inflammatory diseases or pulmonary tuberculosis.

Constitutional obesity can lead to cancer from the breast and female reproductive :, by having an excess fatty tissue within the body, it becomes an outside endocrine organ and actually starts to actively produce hormones-estrogens, whose action and provokes the continuing development of tumors.

Symptoms of Breast Cancer

There are some forms in the growth of breast cancers:

- Nodular form, the most common, is seen as a dense knot of 0.5 to 5 cm or higher, it really is seen as all of the following symptoms;

- Diffuse. All of them are very aggressive, grow quickly, almost lightning speed, the tumor without having clear boundaries, "spreading" in the breast and skin. For the first couple of forms are characteristic warning signs of inflammation: pain of the breast, a bright red color with the skin it raises temperature to 39 degrees C. In view of those symptoms often occur, and errors in carried out patients treated for inflammatory diseases, which are named and therefore are referred to these forms cancer of the breast. When tubular carcinoma breast cancers cover like a "skin" of the contracting and decreasing in proportions.

In some instances, cancer of the breast manifests within the form of metastases inside the lymph nodes for the affected side, often ceases to detect the tumor itself - show hidden cancer of the breast.

For small tumors in the breast, any symptoms arise. The most observant as well as their husbands can easily detect tumor site in the gland by accident, but in a large breast to detect small size hard knot. Revealed a knot might be painful when pressed, round, smooth and agile, this speaks in favor of a benign tumor. Signs of malignancy other: a good knot to touch the stone, its surface is uneven, it really is stationary or slightly shifted, can be firmly fixed on the surrounding tissue or skin, usually painless, can reach a tremendous size (over 3 to 5 cm and quite often 10-15 cm).

Need to assess the surface from the skin on the tumor: the malignant process will probably be observed retraction in the skin, picking up within the folds, wrinkles, an indication of "lemon peel" - a local swelling from the skin in the tumor, may be a direct tumor invasion to the skin surface, then it might be a bright red color and sprawl as "cauliflower."
